The Moirai, also known as the Fates in Greek mythology, are three sister deities who control the destiny of both mortals and gods. Their names are Clotho, who spins the thread of life; Lachesis, who measures its length; and Atropos, who cuts the thread, signifying death. Together, they represent the inescapable fate that governs all beings. The Moirai are often depicted as stern and unyielding figures, emphasizing the belief that fate is predetermined and cannot be altered. They play a crucial role in various myths, illustrating the ancient Greeks' understanding of life, death, and the inevitability of destiny.
